But, before you get to this point, you have to decide a few things, said Eric Feldman, a senior architect in the Global Business Services Optimization Practice at CA. What services are going to be shared; How you are going to measure what is to be shared; How are you going to include truly shared costs, such as datacenter power consumption, as well?
This last can be a real sticking point, said Feldman, and a lot of analysis is going on at companies today to figure out what costs should be borne by all and what costs can be metered out on an individual basis.
But the move toward shared service is happening because, for the business, the benefits far outweigh the headaches for IT. IT becomes more transparent from a cost point-of-view, business managers can see just what they are consuming, upper management can get better picture of the value of IT, and cost savings can be enormous, to name just a few of the many pluses shared services offer. For IT, IT becomes easier to manage and CIOs can make a stronger case that IT, overall, does matter.
The trick to making chargebacks work in this environment is to think like a business manager, not an IT manager.
Its all about management, said SIMs Pickett. It starts with budgets and cash but really its about management practices and strategy. And if that doesnt work? [R]emind them this isnt a democracy, its a corporation.
